Hi there!
1.If you go to the shed while naked, you will get a skill: Dark Gift.
If you get 100 corruption and then this skill and then come back at night, you will see a dragon standing there.
There's an event that will play out afterwards if you speak with it.
2. I will do a remake, but only after I've finished my 20th game. So E.T.A. will be 2025.
